The 2018 regular season is behind us – at least for all leagues not named the Pac-12 and Big West – as conference tournament play kicks off tomorrow (Tuesday) with a lot of postseason ramifications still on the line. We continued to see some significant power shifts this past weekend as Georgia, Florida State and UConn all captured big weekend series against Arkansas, NC State and East Carolina, respectively, a trio of teams that entered the weekend as top 10-ranked clubs. Georgia in particular enjoyed a large jump, going from 20 to 8 as senior outfielder Keegan McGovern, who had hit a home run earlier in Saturday's game, fired a strike to home plate after catching a shallow fly ball in left field to nail the would-be tying run to end the game, and overall series, in dramatic fashion.Florida remains No. 1 at the top despite being swept by Mississippi State in Starkville. While the sweep was huge for Mississippi State and their own postseason aspirations, not to mention the seeding implications it carried for the SEC Tournament, it does not change much in regards to the Top 25 as the Gators have already secured their position as the No. 1 team in the nation by ranking, RPI and likely by overall postseason seeding when the 16 Regional hosts are revealed a week from today.Coastal Carolina re-joins the rankings as a potential Regional host after finishing the season strong by dominating their Sun Belt competition. Dallas Baptist, whose stay in the Top 25 was brief after being introduced last week, fell out after losing their Missouri Valley Conference series to Missouri State.Missouri State was one of eight teams considered for the final spot of this week's Top 25, as were a trio of SEC teams who finished off the regular season with strong, statement victories. While Mississippi State's sweep of No. 1 Florida was mentioned above, South Carolina knocked off Texas A&M to win their fifth straight SEC series and Vanderbilt capped off their up-and-down regular season with a win over Kentucky. Houston wrapped up the American Athletic Conference title a week ago while Louisville and Jacksonville both appear to be dangerous teams heading into postseason play.Congratulations to North Carolina A&T and Texas Southern for already securing berths to the 2018 college baseball postseason by winning the MEAC, and SWAC championships, respectively. A third berth will be determined later today when the Patriot League championship is wrapped up.
