Fantasy Focus Podcast Question

Inspired by the Phillies winningest pitcher only having 6 victories this year (Cole Hamels, now a member of the Rangers), the following question was asked:

Which team's winningest pitcher had the lowest season win total, and how many wins did he have?

If we restrict the search to only starting pitchers (who started in 60% of the games they played), the answer for the lowest win total is 6, which has happened 3 times:

• The 1957 Kansas City Athletics had 2 starters with 6 wins, Ned Garver (6-13) and Alex Kellner (6-5).  This result, however, is dubious for several reasons.  Based on the search criteria, 5 pitchers are eliminated that started at least 7 games because they also appeared frequently as relievers.  In fact, 4 of these 5 relievers had at least 7 wins [Tom Morgan (9-7), Jack Urban (7-4), Virgil Trucks (9-7), and Wally Burnette (7-12)].  Also, the Athletics only played in 153 games that year, giving them less chances to get wins than the current 162 game schedule.
• The 1997 Oakland Athletics (featuring the Bash Brothers) had one starter with 6 wins, and that was Ariel Prieto (6-8).  That A's team was pretty bad (69 wins as a team), but the biggest contributing factor was probably that they had 9 starters make at least 10 starts and no starter with more than 24 starts.  I'm sure their 5.48 team ERA didn't exactly help either.  The team leader in wins was actually reliever Aaron Small, who had 9 wins and 5 losses.
• The 2012 Colorado Rockies had only one starter with 6 wins as well, and that was Jeff Francis (6-7).  Just like the '97 A's, the Rockies were a bad team (64 wins) with a terrible staff ERA (5.22).  Coincidentally, they also had exactly 9 pitchers with 10 or more starts (including a 49 year old Jamie Moyer) and no starter with more than 24 starts.  The leader on the team in wins was actually Rex Brothers, who finished with an 8-2 record from the bullpen.

If we change the search to all pitchers (starters and relievers), the answer is 7, which has happened 4 times (although the 2015 Phillies have a decent shot at taking this record):

• The 1981 New York Mets had two pitchers with 7 wins-- starter Pat Zachry (7-14) and closer Neil Allen (7-6).  However, this was a strike-shortened season so it really should not count.
• The 1987 Cleveland Indians had three pitchers with 7 wins-- the Candy Man Tom Candiotti (7-18),  48 year old knuckleballer Phil Niekro (7-11), and reliever Scott Bailes (7-8)
• The 1996 Detroit Tigers had one pitcher (Omar Olivares) with 7 wins.  I'd say that's not too bad considering the team only won 53 games all season.
• The 2013 Houston Astros, also historically bad with 51 total wins, had one pitcher (starter Jordan Lyles) with 7 wins.
