​CHICAGO — The Chicago Cubs went from not having enough starting pitchers to maybe having too many, a dilemma that can be a problem only if the pitchers don’t buy in.The way things look in early August, manager Craig Counsell eventually will have to play a game of duck, duck, goose, choosing two or three starters for the best-of-three wild-card series and then three or four for the best-of-five division series if the Cubs advance.Of course, a lot can happen between now and October, so it’s way too early for Counsell to speculate on a pecking order. But it’s never too early for everyone else, so let’s guess that Matthew Boyd, Kevin Gausman and Shota Imanaga get first dibs, with Clay Holmes added to the next round, and David Peterson and Edward Cabrera the odd men out.The only certainty is that players will have to put their egos aside in the postseason.“That’s where it takes everybody,” Gausman said Thursday morning in the home dugout before the Cubs beat his former team, the Toronto Blue Jays, 3-2 in 11 innings at Wrigley Field.“I pitched in the seventh inning (in Game 5) of the ALCS last year after starting the whole year. You get to the postseason and you’ve got to do what you got to do. You’re going to be asked to pitch in spots where maybe you haven’t all year, but everybody is on board with that because the goal is winning the championship. Honestly, it’s pretty easy to put yourself to the side when you’re all going towards one goal.”Gausman will make his Cubs debut Friday in Kansas City, Mo., followed by Holmes on Saturday and Boyd on Sunday. That will be seven different starters in seven days for the Cubs, though Colin Rea and Javier Assad have already been told they will be pitching out of the bullpen for now.The Cubs on Thursday called up another deadline acquisition in left-hander Braxton Garrett and sent Tyler Ferguson to Triple-A Iowa. Garrett was a starter in Miami and figures to compete for a rotation job next year but will also move to the bullpen for the rest of the season. Gausman is a free agent after the season, and Holmes figures to decline his option in November to seek a long-term deal.“The way I feel, it kind of lengthens and deepens our group,” pitching coach Tommy Hottovy said of the additions. “We can talk about starters, we can talk about the bullpen guys. To me, they’re all interchangeable and all interconnected in a sense.“If you have good starting pitching, it always lets you push good pitchers you trust like Colin Rea and Javy Assad to the bullpen. Then it gives you an opportunity to use those guys in higher leverage situations. It doesn’t mean they’re not going to start again this year. It’s just where we are right now and how we’re going to move the pieces around.”The upside is that Rea and Assad are stretched out and can throw multiple innings to save the other leverage guys: de facto closer Jacob Webb, Ryan Rolison and newcomer Ryan Zeferjahn. Holmes was a closer
