Day four prelims at the 2017 SEC Swimming & Diving Championships in Knoxville, Tennessee was short and fast with only three events, but certainly had some great races and set up more records to potentially be broken tonight. On the women's side, the 100 backstroke will be the marquee event on the docket. Olympian​ Olivia Smoliga ​of Georgia lead the charge in the preliminary heats, but look for challengers on all sides as four other girls also threw down 51s. On the men's side, Look for ​Chase Kalisz​ of Georgia to drop a big swim tonight in the 200 butterfly, potentially scaring the SEC record and dipping under the 1:40 barrier.

200 BUTTERFLY

Women

SEC Meet Record: 1:52.19 (Camille Adams - Texas A&M, 2014)
NCAA 'A' Automatic: 1:54.01
NCAA 'B' Consideration: 1:59.59

With defending SEC Champion and U.S. Olympian ​Hali Flickinger​ of Georgia out of the picture due to graduation, Chelsea Britt ​will look to capitalize on her huge morning swim of 1:53.90 to give the Bulldogs back-to-back titles in this race. However, don't count out the second seed ​Sarah Gibson ​of Texas A&M who touched in 1:54.43. Gibson is last year's SEC silver medalist and has already won the 500 freestyle and 100 butterfly at this meet. Britt's teammate ​Megan Kingsley​ will also be a major contender in tonight's final. The Bulldog junior was last year's SEC bronze medalist and this event is her bread and butter, so she will make a strong push to stand atop the podium. Regardless of the outcome, you can guarantee this is going to come down to the final 25.

Men

SEC Meet Record: 1:40.59 (Hugo Morris - Auburn, 2016)
NCAA 'A' Automatic: 1:41.86
NCAA 'B' Consideration: 1:47.99

As expected, the Georgia Bulldogs put four swimmers up in the A-final which has huge implications for them holding onto second in the team race. Led by Senior ​Chase Kalisz​ with a 1:42.37, this is anybody's race as second through seventh all touched in 1:43s. Watch out for the defending SEC Champion and meet record holder,​ Hugo Morris​ of Auburn, who barely snuck in the championship final touching 8th with a 1:43.82. ​Pace Clark ​of Georgia and ​Mark Szaranek​ of Florida will be very dangerous as well. Clark was last year's silver medalist and Szaranek has been ON FIRE this meet, barely losing out to Kalisz in the 200 and 400 IM races. Kalisz holds the second-fastest time in the country this year with a 1:40.38, so look for him to break the SEC meet record and dip under the 1:40 barrier.

Women

SEC Meet Record: 50.53 (Gemma Spofforth - Florida, 2009) 
NCAA 'A' Automatic: 51.45
NCAA 'B' Consideration: 55.09

This is undoubtedly going to be one of the marquee races of the night. With five girls under the 52 second barrier and the top two seeds separated only by three hundredths of a second, you can bet this will come down to whoever has the longest finger nails. Defending SEC Champion and U.S. Olympian ​Olivia Smoliga ​of Georgia touched first in 51.10 with Missouri Senior ​Hannah Stevens ​right behind her in 51.13, both NCAA Automatic qualifying times. Don't sleep on ​Kira Toussaint ​of Tennessee, though as she is last year's silver medalist in this race. Kentucky's ​Asia Seidt​ is the wildcard. The Freshman has already put up a 51.50 this season and will look to capitalize on her strong underwaters to make a push for the podium.

NCAA 'A' Automatic: 45.37
NCAA 'B' Consideration: 48.49

The Alabama Crimson Tide rolled their way through prelims of the 100 backstroke, claiming the top two seeds and three of the top six. Led by Senior ​Connor Oslin​ in 45.29 and ​Luke Kaliszak ​in 45.64. the two Bama boys will look to break ​Ryan Lochte's​ longtime SEC meet record of 45.19 from 2005. Both of these guys certainly have the speed and championship final experience to do so. ​Georgia's ​Taylor Dale​ is the wildcard. Last year's SEC silver medalist (behind Oslin), the Senior will look to go out with a bang at his final SEC Championships.

Top 8 Finalists

NCAA 'A' Automatic: 59.04
NCAA 'B' Consideration: 1:02.49

Missouri Senior ​Katharine Ross​' absence left the door WIDE OPEN in this race. Ross, the defending SEC Champion, had to pull out of the meet due to an undisclosed illness. With only two girls under the 1:00 mark this morning and first through eighth separated by nine tenths of a second, it would not be a surprise to see any one of these swimmers take the crown. Even though ​Jorie Caneta​ of Texas A&M is the top seed, Alabama's ​Bridget Blood ​has to be the favorite as she was last year's SEC silver medalist. ​Madison Winstead​ of Kentucky is the wildcard. The Freshman dropped over half of a second from her seed time to scare breaking the 1:00 barrier and will use the excitement of her first SEC A-final to push for the top spot on the podium.

Fabian Schwingenschloegl ​of Missouri holds the fastest time in the country this year with a 51.07 from the Mizzou Invite in November, but he will have to settle for the second seed this morning. ​Nils Wich-Glasen ​of South Carolina threw down a quick 51.58 this morning to claim the sop seed and become the third man to break the 52-second barrier this season. Alabama veteran ​Anton McKee ​took third with a 52.33 just ahead of the defending SEC Champion from Auburn, ​Michael Duderstadt. ​ How about ​Michael Chadwick​, though? The sprint freestyle specialist showed off some serious versatility by taking fifth with a very respectable 52.76. Watch out for ​Peter Stevens ​from Tennessee as well. He has some SERIOUS front-end speed and will look to take it out fast and hold on.
