The Pirates are shutting down lefty reliever Tim Mayza for six weeks, director of sports medicine Todd Tomczyk informs reporters (including Colin Beazley of The Pittsburgh Post-Gazette and Alex Stumpf of MLB.com). The southpaw went on the 15-day injured list over the weekend with a lat strain. Stumpf notes that he’s also dealing with a teres major injury.
A six-week shutdown means Mayza very likely won’t be back until after the All-Star Break. He won’t be cleared to resume throwing until June at the earliest. He’d need multiple bullpen and batting practice sessions before heading on a minor league rehab assignment. A transfer to the 60-day IL is all but assured.
Mayza signed a one-year, $1.15MM free agent deal in February. He’d had a decent run with the Yankees after being released by the Blue Jays. Mayza had been tagged for an 8.03 earned run average across 35 appearances with Toronto. He allowed an even four earned runs per nine through 18 innings in the Bronx, striking out 12 against three walks. The Yanks non-tendered him anyhow, but the solid finish got him a roster spot in Pittsburgh. Mayza looked good in the early going, striking out eight amidst 9 1/3 frames of three-run ball.
The Bucs still have three left-handers in their bullpen. Ryan Borucki and Caleb Ferguson are working in the middle innings, while Joey Wentz can pitch as the long man. Borucki has allowed four earned runs through 10 innings. Ferguson has worked 11 innings of two-run ball. Wentz has surrendered three earned over 12 2/3 frames.
