When last we saw Mike Mayers in a big league game — for St. Louis on Aug. 18 — he was giving up four earned runs in 2/3 of an inning against Pittsburgh. That moved the Ole Miss product’s career ERA in seven appearances to 19.80, not what you wanna see on the back of your baseball card. That ugly number is due mostly to a couple of bad outings. But it is what it is. The Cardinals still have Mayers on their 40-man roster, and he has pitched well in winter ball. Through six starts for Escogido in the Dominican Winter League, Mayers is 2-1 with a 2.43 ERA. After a 12-day layoff, he threw five innings of one-hit, one-run ball on Tuesday. A third-round pick out of UM in 2013, Mayers, 25, has a career minor league ERA of 3.54. Only once in his five minor league seasons has he finished with an ERA above 3.39. He went 5-6 with a 3.28 in 2017 at Triple-A Memphis, splitting time between starting and relieving. He was up for three big league appearances, including that ERA wrecker on Aug. 18. He has to be champing at the bit for his next shot. P.S. Picayune native and Ole Miss alum Braxton Lee, the Southern League batting champ last season, recently was added to Miami’s 40-man roster, and ex-Madison Central High standout Spencer Turnbull made Detroit’s protected roster. Former UM star Bobby Wahl, who made his MLB debut with Oakland in 2017, has been removed from the A’s 40-man. Right-hander Wahl was injured (shoulder) in midseason and didn’t pitch after July 31.
