Worth noting

• Vin Mazzaro stuck out five of six in his two perfect innings in Saturday's 5-3 win over the Red Sox. "All out of the windup, good quality fastballs, good location, nice sliders, and he did a heck of a job," Pirates pitching coach Ray Searage said. "Was very impressive. See what happens. You know, another twist. Here we go. But it's good, it's good to have these tough decisions, and I'm very happy for him, really happy."

• Tony Watson's perfect inning impressed Searage, as well. "He's more confident and more poised out there on the mound and he's got a better idea what he wants to do," Searage said. "It's like your sons are growing up right in front of you and then they talk about certain things, and you're like, 'Hey, that was smart.'"

• Pirates first baseman Matt Curry was involved in an odd double play in the ninth inning. The Red Sox were rallying, with two on and one out. Curry dropped a pop bunt near the third-base line, but fired on to third and then the throw to second completed a rally-killing double play. Had the batter, Blake Swihart, not bunted, an infield fly could have been called. The bunt prevents an infield fly call. "An infield fly is a fair fly ball [not including a line drive nor an attempted bunt]," reads MLB's official rules. The game ended on a strikeout one batter later.

• Pirates manager Clint Hurdle spent Saturday at the team's Minor League complex instead of traveling to Fort Myers for the game against the Red Sox -- a planned decision.
