The Rays have had plenty go wrong, starting with the slew of injuries that started in spring training and have pockmarked much of their season. As a result, they already have used 49 players (three shy of their 2000 team record) including 17 rookies, eight of whom made their major-league debuts. They have had 21 players serve 23 stints on the disabled list, third most in the majors. And they have made a dizzying 129 roster moves since opening day. • But from all that change came opportunity. And here are six of the players who somewhat unexpectedly took advantage, ranked (with all stats through Friday) by the impact they've had thus far: 1. INF Logan Forsythe Stats: .279, 21 2B, 13 HR, 51 RBIs, .787 OPS in 119 games How it happened: Slated for reserve duty going into the season then a job-share at second base with Nick Franklin (after Asdrubal Cabrera emerged as the obvious shortstop starter), he was elevated to full-time duty when Franklin strained an oblique late in the spring and never let go with a tremendous breakout performance. What he's done: Quietly emerged as one of the top all-around second basemen in the majors, ranking in the top six in RBIs (51), HR (13), OPS (.787) and wins above replacement (4.4) in the most extended big-league opportunity of his career. Has been one of the most valuable Rays, sharing team lead in homers and second in RBIs while hitting everywhere from 2-8 in the lineup, playing elite level (Gold Glove?) defense and filling in at 1B when asked, ranking second on team in games played (119). 2. RHP Erasmo Ramirez Stats: 10-4, 3.57 in 26 games (19 starts); 87 K, 32 BB in 116 IP* How it happened: Acquired late spring to supplement injury/illness-ravaged pitching staff (for LHP Mike Montgomery ) from Mariners, who had little use for him as he was out of options. What he's done: After two rough initial outings that had a certain Tampa Bay Times beat writer cracking smart that they should "erase Erasmo," Ramirez has been one of the most effective pitchers not just on the Rays (with a 2.52 ERA) but in the whole AL. Since going into the rotation full time May 14, working under the tutelage of pitching coach Jim Hickey and the team's short-leash philosophy, Ramirez's 10 wins have matched the most in the AL, his .205 opponents' average tops and his 2.61 ERA fourth. 3. RHP Steve Geltz Stats: 2-4-2, 3.39 in 59 games; 54 K, 18 BB in 581/3 IP How it happened: An intriguing September 2014 callup was on the bubble for one of the final bullpen spots until the end of spring training, then quickly worked his way into extensive, versatile and eventually higher-leverage duty, leading the AL with 59 appearances. What he's done: Featuring a fastball he uncannily locates at the top of the strike zone, the 27-year-old rookie has straight up become an integral and durable part of the staff, starting twice and pitching everywhere from the fourth through 11th innings, though primarily in the seventh, and 15 times bridging innings. Allowed only two of first 23 inherited runners to score, tops in AL. Retired 32 consecutive batters in one stretch. 4. LHP Xavier Cedeno Stats: 2-1-1, 1.83 in 49 games; 35 K, 10 BB in 341/3 IP How it happened: Early injuries to Jeff Beliveau (which became season-ending shoulder surgery) and C.J. Riefenhauser , and Jake McGee 's recovery from offseason elbow surgery, left the Rays with no lefties, so they took a cheap flier on Cedeno. He was acquired in late April for cash from the Dodgers (imagine those Matt Silverman - Andrew Friedman negotiations), who got him days earlier from the Nationals, who gave up on him after five so-so appearances. What he's done: Pretty much become one of the most consistent lefty relievers around. Leads AL with 48 appearances since joining Rays, 43 scoreless, including his past 15. Allowed only three of first 35 inherited runners to score. Went team-record 15 straight games without a run or walk. 5. RHP Nathan Karns Stats: 7-5, 3.44 in 24 starts; 133 K, 50 BB in 136 IP How it happened: Rookie was slotted sixth on starting pitching depth chart going into spring, slated, at best, to fill in until LHP Matt Moore returned midseason. But injuries/illness issues with Alex Cobb , Drew Smyly and Alex Colome thrust him into more prominent role, starting Game 2, and he has been a key part of rotation. What he's done: Relying more on curveball than any AL pitcher, he has made an AL-most 18 starts allowing two runs or fewer and five allowing two or fewer hits. Prime subject of Rays' strategy not to go through opposing orders a third time, he has AL-most 12 no-decisions, five when he left in line for a win and bullpen blew it. Leads MLB rookies with 133 strikeouts. 6. C Curt Casali Stats: . 240, 9 HR, 17 RBIs, .885 OPS in 36 games How it happened: Opened season at Triple A but was called up in mid June to replace Bobby Wilson (who was struggling after winning the backup job), then moved into the lineup in late July to replace Rene Rive ra (who was struggling after being handed the starting job after offseason acquisition from Padres). What he's done: Encouraged to let his power play, leads Rays since his callup with nine homers, is second to Yankees' Brian McCann among AL catchers and is close to MLB-leading pace of one per 10.67 at-bats. Has earned praise for defensive improvements, especially game-calling and pitch-blocking. Has thrown out 25 percent (6-of-24) of basestealers.* Started Saturday Short stops • Ben Zobrist finally makes it back to the Trop this week with the Royals, his initial May return wiped out when he was on an injury rehab assignment with Oakland, and he deserves a long and loud ovation. Zobrist was one of the best Rays players and one of the best Rays people during a nine-year stint that goes back to the dark-green days, traded in January (with Yunel Escobar for John Jaso and two prospects, SS Daniel Robertson and OF Boog Powell ) because he was in his last year before free agency. The Rays then spent the $7.5 million he was to make to sign SS Asdrubal Cabrera to a one-year deal, which means he is also in his last year before free agency. Anyway, the Rays have a video tribute of Zobrist planned for Friday's game and maybe another surprise.• RHP Kevin Jepsen also returns this week, to less fanfare but the lingering curiosity of why the Rays would trade a successful high-leverage reliever (for two low-level minor-league pitchers) to a Twins team the Rays are, in theory, fiercely competing with for an AL wild-card spot.• In dealing Wil Myers last offseason, the Rays thought it was wiser to flip two Padres prospects to the Nationals for OF Steven Souza Jr . because they wanted to make sure to improve this year's team and not just the future. Souza has been on the DL twice, though, hitting .214 with 15 homers and 39 RBIs in 89 games. And both those prospects are now in the majors with Washington, 22-year-old RHP Joe Ross a promising 3-5, 3.86 in his first nine starts, 22-year-old INF Trea Turner projected to be a future star. Rays rumblings There's some irony that teams managed by Joe Maddon (Cubs) and presidented by Andrew Friedman (Dodgers) have been no-hit and the Rays haven't. … Chances for promising LHP prospect Blake Snell to get promoted in September seem tied to the Rays' playoff chances — the better, the better. … In case you want to save the date, the AL wild-card game is Oct. 6. … Besides needing his bat, another reason for the Rays to bring INF Richie Shaffer back up from Durham is that they won't be charged with using one of his three options in doing so by Sept. 4 since he would have spent less than 20 days there. … The Rays, per a Sports Business Daily report, will be one of 15 Fox-contracted teams to have games streamed online next season with no blackouts. ... Congrats to baseball ops president Matt Silverman and wife Andrea on the birth of their second daughter, Samantha Rose . … ESPN's Keith Law told WDAE-AM 620 "it's probably time to accept that (3B Evan Longoria ) is just not going to be that player again" and is more likely an "average to slightly above-average regular." … One early 2016 question: Who plays shortstop?
