KANSAS CITY, Mo. — As the Toronto Blue Jays fight for a playoff spot, the club’s minor-league affiliates are winding down. The Dunedin Blue Jays’ season ended Sunday, the Vancouver Canadians begin a championship series Tuesday, and the Buffalo Bisons have just 11 games left, but it doesn’t mean the system has stopped mattering.With notes on Jays who could still come up and help the MLB club in September and other recent prospect developments, here’s the latest on the Blue Jays farm system:Not many hitters to watch down the stretchOn the hitting side, there aren’t many call-up candidates left for Toronto. Utilityman Jay Harry positioned himself for a promotion early in the year, but a midseason injury set him back, and he’s had an OPS under .700 since returning from the injured list in August. The main guy to watch in Triple A, and he’s not a prospect at all, is Anthony Santander.MLB September callups to noteKeith LawSix months after shoulder surgery, Santander is days away from a potential Triple-A rehab assignment. It’s a big ask for the 31-year-old to quickly ramp up, get his timing and prove he can play capable outfield, but that’s what he’ll need to do to get any MLB time this year. We’ve seen Toronto’s issues in left field, with Jesús Sánchez dropping another fly ball Sunday, so there is a path to some playing time if Santander can stay healthy and prove he’s ready. Still, it’s a spot he’ll have to earn. There are no trial at-bats available in a September playoff chase.“Really just focused on the health part up until he does get into games,” manager John Schneider said, “and then kind of evaluate how he’s doing.”Is there any pitching help left?What the Jays really need is for a few more pitchers to emerge. With Jameson Taillon’s latest injury Friday, Toronto has at least one hole in the rotation. The Jays don’t have a clear next starter to promote from Buffalo, so they’ll likely turn to bullpen days and bulk relievers. That’s where the Triple A players come in.Chase Lee and Chad Dallas have maxed out their options this year and would need to clear waivers if they’re sent back down. At this point, the Jays will likely just promote one or both and stomach a potential claim down the line. The recently acquired reliever José Rodríguez, brought over from the Los Angeles Dodgers in a small September trade, is a candidate to make his MLB debut. With a funky delivery and big strikeout stuff, he pitched a scoreless inning with the Bisons this week and owns a 3.28 ERA in 35 2/3 minor-league innings this year.Though fans might clamour for Double-A prospect pitchers Johnny King and Nolan Perry to get a shot, there are reasons the moves are unlikely. Both are already at their career innings maximums. Last year, there was a clear plan to get Trey Yesavage to the big leagues in September. Perry and King haven’t been on that fast track, but plans can always change.Neither has pitched a game with the big-league ball yet, either, as that’s not introduced until Triple A. Many starters see the movement on their pitches change and velocity tick down with the introduction of that slightly different ball. Kade Anderson, the top pitching prospect in baseball called up by the Seattle Mariners recently, is working through that exact issue after a promotion from Double A. Even though Yesavage looked ready for the Jays late last year, they still gave him 17 1/3 innings with Buffalo before a late-September promotion.
