BALTIMORE — Chicago Cubs manager Craig Counsell wants to keep certain parts of the club’s operation walled off, preferring to stress that it’s always a group effort, rather than spotlight members of his coaching staff: “Blame me, give everybody else credit.”As the Cubs simultaneously dealt with a barrage of pitching injuries and a collective offensive slump this season, Counsell did not see a bigger concern or a more manageable situation: “One or the other won’t be good enough.”With the Aug. 3 trade deadline approaching, Counsell won’t be viewing the rotation and the bullpen, exclusively, in terms of priorities. A pitching staff is so connected that there can be different ideas about game-planning and packing the roster with more talent.But even Counsell acknowledges that certain players can have an outsized impact, the skills and presence to make other pieces fit together better.Matthew Boyd started Chicago’s first playoff game last year and Opening Day this season. He was picked for the All-Star Game last summer and added to Team USA for the World Baseball Classic this spring. The Cubs went more than halfway through this season still waiting for him to get into a rhythm.Boyd found it in Tuesday night’s 5-2 win over the Baltimore Orioles, throwing six scoreless innings at a rain-soaked Oriole Park at Camden Yards. The experienced lefty saw an uptick in velocity early while regaining a sharper feel for his four-pitch mix at game speed. He allowed only three singles and two walks and finished with seven strikeouts. In front of a crowd of 16,200, he submitted his first quality start in two-plus months.
