SAN FRANCISCO -- Sam Dyson arrived in San Francisco with an ERA this season that left a lot to be desired. It was 10.80 after 17 outings with the Rangers. He was traded June 6.
Since then, though, Dyson has regrouped, posting plenty of efforts that have Giants manager Bruce Bochy be proud of his progress. Tuesday was just the latest iteration in Dyson's evolution. He entered in the ninth, pitched two innings of scoreless ball, picked up his first win of the season and helped the Giants walk off with a 2-1 win in 10 innings.
His ERA with the Giants? A cool 2.93. It ranks third among Giants pitchers.
"Buster [Posey] called some nice pitches, defense obviously played well behind me and our team came back and battled," Dyson said.
Bochy's appreciation for the 29-year-old includes more than a solid defense, though. Dyson has the mechanics necessary to stifle Major League batters -- even if that didn't show through at his previous stop.
"He's done a really nice job," Bochy said. "He's got great stuff. You look at his body of work last year, really in the Major Leagues -- he's used to pitching in high-level situations. He's got the stuff to do it."

After allowing a leadoff walk in the ninth, Dyson retired the next three Indians batters. In the 10th, the Giants stuck with Dyson. He delivered, tossing a 1-2-3 inning. Along the way, he shut down Tribe hitter Bradley Zimmer, who had a two-hit night.
Dyson has assumed a closer role for the Giants since Mark Melancon, the team's prized offseason acquisition, again landed on the disabled list with a right pronator strain. Though he's eligible to return, the Giants don't want to rush Melancon's rehab. Knowing they have Dyson ready to go certainly doesn't hurt, either.
Dyson has recorded four saves over his last six outings, building his career total to 44. He's allowed one earned run and six hits over that span.
"He's got the poise that you like from a closer," Bochy said. "He's accustomed to going one inning. But we've pushed him, and he's handled that well."
Added Giants starter Ty Blach: "Sam's done a really nice job for us since coming over. He's been a big piece for our bullpen."
