Monday’s matches at Roland Garros feature a battle between two South American clay specialists and a matchup pitting one of the game’s rising stars against a struggling American.

Juan Monaco v. Federico Delbonis

Juan Monaco and Federico Delbonis have lost 15 of their last 20 combined Grand Slam matches. Both men were knocked out in the first round of the Australian Open, and although one of them is guaranteed a spot in the Round of 64 at Roland Garros, getting there isn’t going to be easy.

On paper, this is one of the closest first-round matches of the tournament. Despite the fact that Delbonis’ ranking has taken a bit of plunge this year after he lost in the first round of Buenos Aires, which he won in 2014, the lower-ranked Argentine will be a stern challenge for Monaco.

They have met twice before, with the meetings being split and Delbonis holding the sole victory on clay. Last week was particularly successful for Delbonis, where he reached the semifinals in Geneva, beating top seed Stan Wawrinka along the way. Monaco had a pretty successful week as well, making the quarterfinals of Nice before losing to eventual finalist Leonardo Mayer.

It’s worth noting that throughout the European clay court season, Monaco was playing in the main draws of big events like Barcelona, Madrid, and Rome, whereas Delbonis was fighting through qualifying draws and challengers.

Delbonis plays with a pretty extreme grip and generates a ton of topspin off his forehand side via his upward arching swing and substantial body rotation. On clay, the bounce of the balls off his forehand side are accentuated, meaning Monaco will need to be proactive in stepping in and taking the ball early, particularly off his backhand side. Delbonis is aggressive in attacking the short ball and is able to penetrate the court off both wings.

Monaco should look to move Delbonis laterally and north and south in order to keep the big man hitting while moving. Delbonis thrives when given time from the center of the court, making it imperative that Monaco avoids giving him room to dictate.

If Monaco can keep this match long and drawn out, which I suspect he will, it will be a significant test of Delbonis’ mental and physical strength. Given his lack of success at majors, beating a skilled clay court player like Monaco at Roland Garros won’t be an easy ask.

Prediction: Monaco in five sets

Sam Querrey v. Borna Coric

Sam Querrey reached the Houston final this year and holds a 6-4 record on clay in 2015. Unfortunately, this small sample size of success is not representative of the rest of his career. The American has performed far worse on clay than the other two surfaces and has only ever won more than one match at Roland Garros one time. Additionally, Querrey has never beaten a player ranked higher than him at the French Open.

Coric’s Grand Slam resume is very small. He’s only played the main draw of a Grand Slam twice and has won just one match total.

The American and the Croat will be meeting for the first time on Monday in a match that presents a nice contrast of styles between two players who have the potential to push each other the distance. After Sunday’s lack of long matches, a drawn-out battle here would surely be welcomed.

Querrey and Coric both played last week in Nice. Coric reached the semifinals before losing to Mayer, and Querrey lost in the second round to Monaco. The only notable clay court result thus far for either of these two this season was Querrey reaching the Houston final for the second time in his career.

Querrey is not known to be the most patient player out there, so look for Coric to drive the American bonkers with his high level of defending. Querrey has the capacity to blow through almost anyone with his serve and forehand, but over the course of five sets on a slower surface against a talented defender, Querrey is going to have to pick his spots well and continually expect every shot to come back.

Querrey is the favorite, but this is a good matchup for Coric on clay, providing a great opportunity for him to reach the second round of Roland Garros for the first time.

Prediction: Coric in five sets
