In addition to the signings of Daniel Ortiz and Curtis Partch, which we already knew about, the Pirates have announced a variety of minor league signings today.
RHP Deolis Guerra
RHP Wilfredo Boscan
LHP Robert Zarate
INF Cole Figueroa
Guerra and Boscan, of course, were in the Pirates' system last year, and getting Guerra back in particular is a nice bit of news -- if he and his floating changeups are in the big-league bullpen for a long stretch, that isn't good, but he's excellent minor-league depth, and he was terrific for Indianapolis last year. Boscan is a fairly generic minor-league starter who the Pirates promoted to the big leagues several times last year but never put in a game.
The 28-year-old Zarate will likely join Guerra in the Indianapolis bullpen. He posted a 3.57 ERA for the Rays' Triple-A affiliate in Durham last year, striking out 49 and walking 15 in 40.1 innings. His track record is a bit spotty because he spent a fair amount of time pitching in the minor leagues in Japan, but his numbers last season are modestly promising.
Figueroa, 28, played mostly shortstop and third base for Triple-A Scranton/Wilkes-Barre in the Yankees system last season, hitting .292/.355/.359. He should be infield depth at Indianapolis, although it's worth noting that he has a career .375 minor-league OBP. On paper, Figueroa looks a lot like Dean Anna, another former Yankees shortstop who got on base a ton and who played briefly in the Pirates' system in 2014.
