First, a few things about May 28th.
On May 28th, 2013, the Red Sox were 32-21, in first place, and had Ryan Dempster pitching. Dempster lost, but pitched well enough to win by allowing 2 runs over 7 innings.
On May 28th, 2007, the Red Sox were 35-15, in first place, and had Curt Schilling pitching. It was vintage Schilling. 7 innings, 1 run, 10 strikeouts.
On May 28th, 2004, the Red Sox were 30-18, in first place, and had Pedro Martinez pitching. He wasn't vintage but he was efficient, throwing 7 innings and striking out 9, though he allowed 4 runs.
No recent Red Sox team has won a World Series with a record below .500 as of May 28th on any given season. The 1967 Impossible Dream reached the World Series, but they were only a single game below .500 on May 28th that year.
That being said, it's still too early to completely count out the 2015 Boston Red Sox. Highly touted prospect Eduado Rodriguez takes the mound tonight. Over the course of 100 minor league starts, Rodriguez has an ERA of 3.23. He currently has a 2.98 ERA with the Pawtucket Red Sox, and has a complete game to go along with 8 starts. If he has a solid outing, it could turn things around for the Red Sox.
Eduardo Rodriguez joins a long line of players to join the Red Sox at a time when the team is looking for a spark. Around the same time in 2003, Shea Hillenbrand was traded to the Arizona Diamondbacks for closer Byung-Hyun Kim.
Another trade in 2003 may have helped spark the team as well. A player who has been called Dave Kapler, Gabe The Babe, and he makes women swoon.
Gabe Kapler was acquired at the end of June in 2003. At the time the team was middling through a losing month. In Kapler's first two games, he nearly hit for the cycle in his first game, and homered twice in his second game. It's not clear in the box scores if Kapler had a huge part in the turnaround for the Red Sox, but considering his tenure with the team, it's likely it had some impact.
As the Red Sox hopes begin to become more questionable, the hope is that Eduardo Rodriguez is the answer that the team needs. Can a rookie suddenly become an ace? Doubtful, but maybe a strong performance inspires the rest of the team.
