Which pitcher holds the record for most wins in major league baseball?

Rube Marquard won 19 consecutive games in 1912... I don't think that record has ever been broken. If you're interested in Baseball records, I recommend the book <a class="url" target="_blank" rel="nofollow noreferrer" href="/to/?target=http://www.booksonboard.com/index.php?BODY=viewbook&BOOK=17728">Clearing the Bases (the ebooks and audiobooks version)</a>. It's really interesting... parts are a little sad bc baseball isn't the clean sport it used to be... but still interesting.
