The Pirates acquired Chris Stewart from the Yankees to serve as Russell Martin’s backup, but now the 31-year-old catcher is likely headed for surgery after injuring his knee in a game last week.
Stewart didn’t figure to play much for the Pirates considering he’s a career .214 hitter and Martin started 117 games last year. In his place 25-year-old former first-round draft pick Tony Sanchez will make the Opening Day roster and may end up seeing more action than Stewart would have if the Pirates don’t want to let him rot on the bench.
Sanchez’s prospect stock dipped a ton in 2011 and 2012, but the former No. 4 overall pick hit .288 with 10 homers, 26 doubles, and an .872 OPS in 76 games at Triple-A last season. Martin is an impending free agent, so the Pirates may try to groom Sanchez to take over behind the plate full time in 2015.
