PORT CHARLOTTE — Ashlee Rowe's reputation as a good babysitter willing to help out boyfriend Kirby Yates' teammates preceded her when she reported to Rays spring training last year.Soon Jaime Edmondson and Evan Longoria had her booked to watch daughter Elle, Kim and David DeJesus hired her for their son, and others were lining up."I was like, I can't watch all these kids by myself," Rowe said, "so I decided I would start hiring people to do it for me."From that start, Rowe has launched a business with immense potential for expansion, forming Home Run Sitters, an agency geared exclusively to providing child care for pro athletes."It's been a full year now, which is crazy," Rowe said. "I found a niche, and as long as I continue to grow and I've got great feedback, I think I'll be pretty successful."Rowe has built a solid base, with a staff of three dozen babysitters working throughout Florida and Arizona now and partnerships with agencies in California and New York to provide service there, mostly for baseball families.But she has much bigger plans, wanting to have all spring training and major-league cities covered (for both home-team and visiting players), add more clients from the NBA, NFL, NHL and other sports, and land contracts to provide family child care services that teams can offer at stadiums and arenas."I think it's awesome," said Yates, a reliever who made his big-league debut in June. "It started with her just throwing around the idea and a year later she's made significant progress. Now it's an actual business and it's working. I'm extremely proud of her because she's done absolutely everything. … She's a smart girl, and she understands a lot. It's all her, and it's pretty cool."Rowe, joking about learning how much work she can get done from the couch in her pajamas, knows that the personal relationships help but that the quality of service ultimately will be the key to success, with word-of-mouth and good referrals critical. She insists on certain experience, education and age requirements for the sitters she hires, doing the usual background/reference checks plus personal interviews with each.Also, she has a firsthand understanding of the needs of her client base — short notice, odd hours, privacy and discretion, such as the sitters not sharing photos or their location on social media. (Rates vary by city and family size, but Rowe said $20 an hour is typical.)"I think it's a really genius idea she came up with," said Edmondson, who used the service throughout the offseason in Arizona, too. "There's an extra level of accountability with Ashlee and her company because she knows in order for her business to thrive, she's got to have done her background work."With baseball and other athlete families, you've got to be careful who you invite into your life and into your home and to be with your children because it's scary. … So I felt comfortable right away using her knowing she'd have to look at me and other people on the team, and that the only way her business was going to grow was to have good people working for her and to get good referrals."Rowe said she has had no major issues arise yet. She acknowledges it can be awkward mixing her business — she still does sitting herself — and social interests, but doing so motivates her "to work 10 times harder" to make things right.And there have been a few funny moments.While providing the child care at a December Pro Athletes Outreach event, Rowe was certain she recognized the dad dropping off a young daughter.A few moments and a couple of texts later, she realized it was Chris Davis, who had homered off Yates in an August game. "I said my fiance made his debut last year and I'm pretty sure you hit a homer off him," Rowe said. "He's like, 'Sorry.' So that was funny."Rowe, who worked previously as a nanny, teacher and volleyball coach, is still learning some of the business aspects of running a company and pondering the benefits of trying to get on the Shark Tank business incubating show. She and Yates, who met in college and have been together seven years, got engaged in January and figure someday they will have their own kids.But for now, via homerunsitters.com, she is keeping plenty busy taking care of others.
