The New York Yankees' Old-Timers' Day, meant to celebrate the 2009 World Series team, turned sour as rookie pitcher Will Warren struggled significantly in a 9-2 loss to the last-place Rockies. Warren, filling in for injured starters, allowed six runs (five earned) on seven hits over three innings, including two balks and a catcher interference. His ERA ballooned to 9.68 as he fell to 0-2 in his MLB career. Despite striking out six, Warren failed to prevent runs in key moments, notably a four-run third inning. The Yankees' offensive efforts, including a home run by Alex Verdugo and an RBI double by Jazz Chisholm Jr., were insufficient to overcome the deficit. The Yankees now await the return of injured pitchers to stabilize their rotation.
