Gerrit Cole improved to 6-5 on the season after yielding two runs over six innings against the Diamondbacks on Friday. Working on more than a week of rest, Cole struck out five and walked two. The rookie right-hander has now walked two batters or fewer in 11 out of his 12 starts in the big leagues. The Pirates are watching his innings carefully, but he's expected to be available if the club makes the postseason. He'll bring a 3.88 ERA and 1.14 WHIP into a favorable matchup against the Padres in San Diego next week.
