Giants’ Span becoming iron man with Pagan, Pence out

Giants’ Span becoming iron man with Pagan, Pence out With corner outfielders Angel Pagan and Hunter Pence injured, manager Bruce Bochy has not been able to rest Span as often as he would like. Span has started 41 of the past 44 games and 57 of the Giants' 64 games overall. [...] with two important bats missing, Span has had to done the iron-man armor. Even if those guys were healthy I'd be still wanting to play every day. Span might benefit from a more rest. The more carries I get - the more at-bats I get - the more in a groove I get in as well. For his career, Span has hit .248/.311/.364 in June, his weakest month, but .314/.390/.398 in July, his strongest. Samardzija admitted he was not as aggressive in the strike zone as before. Bochy said Samardzija needs to use his secondary pitches more, as he did during a hot start. "Like all these pitchers he's got to tweak it a little bit to get things back in line," Bochy said. Angel Pagan was expected to play in the second of three rehab games for Triple-A Sacramento on Sunday. Matt Cain (hamstring strain) will come off the disabled list on his first eligible day Monday and start against the Brewers on the fourth anniversary of his perfect game. Henry Schulman is a San Francisco Chronicle staff writer. The Brewers announced that Matt Garza, their No. 2 starter last year, will make his 2016 debut against the Giants on Tuesday.
