The Yankees will have a chance to clinch a playoff berth, the American League East Division title and home-field advantage throughout the AL playoffs.
"There's a lot of really good things that could happen for our club," Girardi said. "We have an opportunity to accomplish what we set out to at the beginning of the year, the first step of it. This week could be very telling."
The Yankees entered Monday 46-27 at Yankee Stadium this season, and Girardi is hoping the return home will help his team return to form after a rough road trip in which the Yankees scored three runs or fewer in five of 10 games. The Yankees will play the one game against the Twins before a four-game series against the Rays and a three-game set with Boston. The Yankees started the day leading Boston by 4 1/2 games in the AL East and Tampa Bay by 6 1/2.
"We haven't played as well as we have most of the year over the past 10 or 11 days. We haven't swung the bats like we're capable in a lot of those games," Girardi said. "We need to get back on track."
