Missouri rose three spots to No. 23 in the Collegiate Baseball NCAA Division I poll, which was released Monday.
The Tigers took two of three games from then-No. 6 South Carolina in a weekend series and are 5-1 in the SEC. The Gamecocks slipped to No. 13 in the rankings.
Missouri, 18-6 overall, is tied for first place in the SEC East division with Vanderbilt.
The Tigers, who face Arkansas-Pine Bluff on Tuesday and Wednesday, play at top-ranked Texas A&M this weekend.
The Aggies lead the SEC West with a 5-1 record and are 24-1 overall.
Last spring, Missouri finished 20-33 overall and lost its last 15 conference games, going 6-24 in the SEC and missing the postseason conference tournament.
The Tigers didn’t crack the USA Today Baseball Coaches Poll top 25 but did receive the 30th most votes.
Missouri also received votes, but remained outside the top 30 ranking in the National Collegiate Baseball Writers Association poll.
LSU, Vanderbilt and Texas A&M are the top three teams in the poll with Florida sixth, South Carolina seventh and Mississippi State 29th from the SEC.
The Tigers, who also received votes in the D1Baseball.com top 25, were not represented on Baseball America’s top 25.
