With a series win over Stanford, Oregon State not only continued their recent dominance over the Cardinal, they also re-claimed the second spot in the Top 25, which is where they opened the season and stayed until early April. Since that time the No. 2 spot in the rankings has been held by either NC State and Stanford, who now sit at Nos. 3 and 4, respectively.Florida continues to be ranked the No. 1 team in the nation, a spot they have yet to relinquish, and at this point in time it's hard to imagine them falling from that spot, even if they slip up against Mississippi State in Starkville next weekend to close out the regular season. The Gators enjoyed another strong week, this time beating an upstart Georgia squad that managed to salvage the final game of the weekend series.Both Stetson and Tennessee Tech were introduced to the Top 25 a week ago and both clubs enjoy big jumps this week as they continue to win in impressive fashion. Stetson continued their dominance in the ASUN by sweeping Florida Gulf Coast in Fort Myers, while Tennessee Tech enjoyed a sweep of their own over visiting Eastern Kentucky.A pair of SEC teams, Ole Miss and Arkansas, have each spent most of the 2018 season ranked within the top 10, and both clubs enjoyed impressive weekend sweeps that helped solidify their ranking, not to mention that both teams are likely to be National hosts come June. Duke took two of three against North Carolina this weekend, and while they are still behind the Tar Heels in the Coastal Division of the ACC, Duke moves ahead of UNC in the rankings.After Texas A&M was swept by Arkansas in Fayetteville they fall out of the Top 25 despite their still-lofty RPI. Taking their place in the rankings is Dallas Baptist, a team that not only has been dominant in The Valley, but also completed their second of two victories over Texas Tech in midweek action to go 4-0 on the week.Be sure to tune in to Perfect Game College Baseball on SiriusXM ESPNU channel 84 from 7-9 p.m. ET as we recap all of the week's action while looking ahead to the final week of the regular season.Louisville, Coastal Carolina.
